Abstract: Abstract of the Disclosure A thermal transfer means comprising a flexible bag or pouch filled with a chemically inert, electrically nonconductive, nonflammable, essentially gas-free, thermally stable, thermally conductive, body of liquid comprising fluorochemical liquid. Said bag is fabricated from a flexible, durable plastic film that has low permeability to air and the fluorochemical liquid.  The configuration of the bag is conformable to adapt to the geometry of the space, formed between the surface of a heat generating component or components and the surface of a heat sink, into which the bag is inserted, thereby contacting said surfaces and providing a thermal conduction path for heat generated by the heat generating component during operation from said component to the heat sink.  The liquid has a boiling point such that it does not boll at the highest operating temperature of the device.  Also provided is a method for making and filling the bag such that after sealing the bag is substantially gas free.

Abstract: ABSTRACT PROCESS FOR REMOVING SULFUR MOIETIES FROM CLAUS                     TAIL-GAS            Claus tail-gas containing H2S and SO2 in a mol ratio of 2:1 is passed in contact with a catalyst-adsorbent bed at a temperature of 135 to 150°C and a space velocity of 50 to 1500 h-l whereby elemental sulfur produced by the reaction of H2S  and SO2 is deposited upon  and/or  adsorbed on  the bed.    The resulting  sulfurous  gas  mixture  is  cooled  by indirect heat exchange to a temperature of 120  to 135°C and liquid elemental sulfur is recovered, the sulfurous gas thereafter being cooled and diluted by adding cool inert gas thereto to maintain the water partial  pressure  below   the   saturation   vapour pressure,  and  the  cooled  diluted  gas  mixture  is contacted  with  a  bed  of  catalyst-adsorbent  at  a temperature of 90 to 125°C whereby further elemental surfur is produced by the reaction of SO2 and H2S.            The  elemental  sulfur  deposits  upon  and/or  is adsorbed on the catalyst-adsorbent and the resulting purified gas is incinerated and discharged to the atmosphere.   In one embodiment,  the gas  from the indirect  heat  exchange  step  is  contacted  with catalyst-adsorbent at 120 to 135°C before cool inert gas  is  mixed  therewith,  elemental  sulfur  being deposited  upon  and/or  adsorbed  on  the  catalyst-adsorbent.   Elemental  sulfur  is  removed from the catalyst-adsorbent beds by a hot,  inert purge gas which is cooled for sulfur recovery.   The purge gas is cooled at the end of the surfur-recovery step to cool the catalyst-adsorbent beds for a further cycle of sulfur recovery from Claus tail-gas.

Abstract: Abstract The invention relates to a wheel set guidance for trucks of rail vehicles,  especially commuter traffic vehicles.          With such vehicles, it is desirable to have a continuously extending floor on as low a level as possible. Pursuant to the present invention,  a truck with free wheels is proposed where the free wheels are mounted in pedestal bearings that are connected with a frame structure that is connected to the truck frame in such a way as to be pivotable in a vertical direction.  One of the wheel sets can be driven, with the free wheels being connected in a twist-resistant manner via gear means, so that from a motion standpoint the   same  effect  is achieved as if the driven wheel set were connected with a rigid wheel sat shaft, but without this shaft being in the way of the floor, so that a vehicle equipped with this truck can have  a continuously extending floor on a low level.

Title: Binder for coated abrasives
Inventor: BUCHAAN SCOTT
IPC: B24D3/34
Filed: 1989-08-03
Granted: 1992-01-28
Abstract: ABSTRACT OF THE DISCLOSURE                      This invention relates to abrasive products having a resinous binder which bonds abrasive granules to a backing sheet or to a fibrous sheet.       In the manufacture of coated abrasives, a make coat and abrasive granules are first applied to a backing, the make coat is partially cured, then a size coat is applied, and the resulting construction is fully cured. Generally, the binders for the make coat and size coat are thermally curable resins.       In order to obtain proper coating viscosities with thermally curable resins, solvent is added to these resins.  With polyester or cellulose backings, however, curing temperatures are limited to about 130°C.  At this temperature, cure times are long.  The long cure time along with the requirement of solvent removal necessitate the use of festoon curing areas.  Festoon curing areas require large amounts of space and enormous amounts of energy.       The present invention provides an abrasive product comprising abrasive grains bonded to at least one major surface of a backing sheet by a binder formed from a blend comprising radiation curable monomer and a thermally curable resinous material.  The radiation curable monomer can be selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group, isocyanate derivatives having at least one terminal or pendant acrylate group, and multifunctional acrylate monomers.  The thermally curable resinous material is preferably a member selected from the group consisting of phenolic resins, urea-formaldehyde resins, melamine-formaldehyde resins, and epoxy resins.  The binder can be used to form the make coat, size coat, both make and size coats, or as a backing treatment for a coated abrasive product.  The abrasive products of this invention can be prepared without the use of festoon curing areas.

Abstract: METHOD OF IDENTIFICATION OF WELL DAMAGE AND DOWNHOLE IRREGULARITIES                 Gary R. Holzhausen Gregory S. Baker Howard N. Egan ABSTRACT OF THE DISCLOSURE     A method of testing a water or petroleum well to obtain information about well features, especially that part of the well beneath the ground surface, is described.  The method is especially useful in detecting problems or irregularities in the well such as stuck tools, casing damage, damaged zones in an uncased well, or debris in a well.  The method involves creating oscillations in the fluid pressure in the well.  Transducers measure the pressure oscillations.  The measured pressure oscillations are used to determine resonant frequencies.     The measured resonant frequencies are used to determine the characteristic impedance and the depth of each reflector in the well, after removing resonances caused by known reflectors.  It is then possible to determine the nature of each unknown reflector based on suspected problems or the well's operational history.

Abstract: A rotatable shaft/thrust plate combination is disposed within a sleeve to form a first clearance space between the shaft and the sleeve and a second clearance space between the thrust plate and the sleeve.  The external faces of the thrust plate are exposed to air.  The clearance spaces are filled with a liquid lubricant placing the bearing in a vacuum chamber above a liquid lubricant; evacuating the chamber to a pressure below atmospheric pressure; submerging the bearing into the lubricant; and raising the pressure in the chamber to atmospheric pressure; and the sleeve includes pressure equalization ports connecting the first and second clearance spaces.  Surface tension dynamic seals are provided between axially extending surfaces of the thrust plate and sleeve.  The equalization ports balance the hydrodynamic pressures in the lubricant to prevent the lubricant being pumped through one of the dynamic seals.  The resulting bearing provides high precision with low repetitive and non-repetitive runouts.  The bearing provides hydrodynamic support of both radial and axial loads and the bearing seal is relatively insensitive to orientation of the spindle and minimizes the generation of debris and contaminating particles.

Abstract: In an FM television signal angle modulated with luminance and chrominance information, there exists a high degree of correlation between picture elements occurring one line period apart. In an effort to steer the pass band of a tunable bandpass filter to the instantaneous frequency of the incoming television signal, a steering signal is developed which utilizes this high degree of correlation. For NTSC systems, luminance information is delayed by one-line period (63.5 us in the U.S.A.) and combined with suitable delayed chrominance information to form the filter's steering signal. For MAC systems, one-line delayed luminance and two-line delayed chrominance information are alternately applied to the filter as its steering signal. By steering the pass band of the filter to the incoming signal, maximum signal will be captured with minimum noise, enhancing the signal-to-noise ratio of a color television system.
